図1は、本実施の形態の車両用電装品制御装置の構成を示すブロック図である。   FIG. 1 is a block diagram showing the configuration of the vehicle electrical component control apparatus according to the present embodiment.

車両用電装品制御装置1は、車両の運転手2の眼3の位置を検出する検出部11と、検出部11と眼3との位置関係から運転手2の座高や頭の振れ具合などの身体特性を推定し、また、車両に設けられた電装品と眼3との位置関係を推定し、電装品と眼3との位置関係及び運転手2の身体特性から運転手2が電装品を見た場合の視線を推定する推定部12と、推定した電装品と眼3との位置関係や推定した運転手2の視線に基づき電装品の位置設定を変更する制御部13と、電装品の位置設定を変更することまたは電装品の位置設定を変更していることを運転手2に通知する設定変更通知部14とを有している。車両用電装品制御装置1は、車両のルームミラー4に内蔵されたり、ステアリングコラムカバー上に載置されたりする。   The vehicle electrical component control apparatus 1 includes a detection unit 11 that detects the position of the eye 3 of the driver 2 of the vehicle, and the seat height of the driver 2 and the head swinging state based on the positional relationship between the detection unit 11 and the eye 3. The body characteristics are estimated, and the positional relationship between the electrical components provided on the vehicle and the eyes 3 is estimated. From the positional relationship between the electrical components and the eyes 3 and the physical characteristics of the driver 2, the driver 2 selects the electrical components. An estimation unit 12 that estimates the line of sight when viewed, a control unit 13 that changes the position of the electrical component based on the estimated positional relationship between the electrical component and the eye 3 and the estimated line of sight of the driver 2, and A setting change notification unit 14 that notifies the driver 2 that the position setting is changed or the position setting of the electrical component is changed. The vehicle electrical component control device 1 is built in a vehicle rearview mirror 4 or placed on a steering column cover.

図2は、本実施の形態の車両用電装品制御装置1の動作手順を示す図である。   FIG. 2 is a diagram illustrating an operation procedure of the vehicle electrical component control apparatus 1 according to the present embodiment.

車両用電装品制御装置1は動作を開始すると、制御部13は車両が走行中であるか否かの判定を行う(ステップS101)。車両が走行中である場合(ステップS101、Yes)には、車両用電装品制御装置1は動作を終了する。   When the vehicle electrical component control device 1 starts operating, the control unit 13 determines whether or not the vehicle is running (step S101). When the vehicle is traveling (step S101, Yes), the vehicle electrical component control device 1 ends the operation.

車両が走行中でない場合(ステップS101、No)、例えば、停車中や駐車中である場合には、検出部11は、カメラで運転手2を撮像し、運転手2の眼3の位置を検出して、その結果を推定部12に出力する(ステップS102)。   When the vehicle is not running (step S101, No), for example, when the vehicle is parked or parked, the detection unit 11 captures the driver 2 with the camera and detects the position of the eye 3 of the driver 2. Then, the result is output to the estimation unit 12 (step S102).

推定部12は、検出部11と眼3との距離、垂直角度、及び水平角度といった位置関係から運転手2の座高や頭の振れ具合などの身体特性を推定する(ステップS103)。また、推定部12は、ルームミラー4、ドアミラー5、インパネディスプレイ6、カーナビディスプレイ7などの電装品と眼3との位置関係を推定し、電装品を運転手2が見た場合の視線を推定する(ステップS104)。運転手2の視線の推定は電装品と眼3との位置関係及び運転手2の身体特性から行う。そして、推定部12は、推定した運転手2の視線を制御部13に出力する。制御部13は、推定した電装品と眼3との位置関係や推定した運転手2の視線に基づき、運転手2が快適に運転するための電装品の位置設定を算出する(ステップS105)。   The estimation unit 12 estimates body characteristics such as the sitting height of the driver 2 and the degree of head shake from the positional relationship such as the distance between the detection unit 11 and the eye 3, the vertical angle, and the horizontal angle (step S103). The estimation unit 12 also estimates the positional relationship between the electrical components such as the room mirror 4, the door mirror 5, the instrument panel display 6, and the car navigation display 7 and the eyes 3, and estimates the line of sight when the driver 2 views the electrical components. (Step S104). The gaze of the driver 2 is estimated from the positional relationship between the electrical component and the eye 3 and the physical characteristics of the driver 2. Then, the estimation unit 12 outputs the estimated line of sight of the driver 2 to the control unit 13. Based on the estimated positional relationship between the electrical component and the eye 3 and the estimated line of sight of the driver 2, the control unit 13 calculates the position setting of the electrical component for the driver 2 to drive comfortably (step S105).

そして、制御部13はステップS105で算出した電装品の位置設定が現在の位置設定と同じであるか否かを判定する(ステップS106)。ステップS105で算出した電装品の位置設定が現在の位置設定と同じである場合(ステップS106、Yes)には、車両用電装品制御装置1は動作を終了する。   Then, the control unit 13 determines whether or not the position setting of the electrical component calculated in step S105 is the same as the current position setting (step S106). When the position setting of the electrical component calculated in step S105 is the same as the current position setting (step S106, Yes), the vehicle electrical component control apparatus 1 ends the operation.

ステップS105で算出した電装品の位置設定が現在の位置設定と同じではない場合(ステップS106、No)には、制御部13は設定変更通知部14のディスプレイによる表示やスピーカによる音声で運転手2に電装品の位置設定を変更することを通知する(ステップS107)。そして、制御部13は電装品の位置設定を変更し(ステップS108)、車両用電装品制御装置1は動作を終了する。   When the position setting of the electrical component calculated in step S105 is not the same as the current position setting (step S106, No), the control unit 13 displays the driver on the display of the setting change notification unit 14 and the sound from the speaker 2. Is notified that the position setting of the electrical component is to be changed (step S107). And the control part 13 changes the position setting of an electrical component (step S108), and the electrical component control apparatus 1 for vehicles complete | finishes operation | movement.

なお、車両用電装品制御装置1は、ステップS101の車両が走行中であるか否かの判定を省略して、車両が走行中であっても電装品の位置設定を変更できるようにしてもよい。また、車両用電装品制御装置1は、運転手2に電装品の位置設定の変更を通知するのを、電装品の位置設定を変更し始めてからにしてもよい。   Note that the vehicle electrical component control device 1 omits the determination of whether or not the vehicle is traveling in step S101 so that the position setting of the electrical components can be changed even when the vehicle is traveling. Good. Further, the vehicular electrical component control apparatus 1 may notify the driver 2 of the change of the position setting of the electrical component after the change of the position setting of the electrical component is started.

図3は、本実施の形態の車両用電装品制御装置1の動作を説明するための図であり、車両用電装品制御装置1を搭載した車両9の俯瞰図である。   FIG. 3 is a diagram for explaining the operation of the vehicle electrical component control apparatus 1 according to the present embodiment, and is an overhead view of the vehicle 9 on which the vehicle electrical component control apparatus 1 is mounted.

車両用電装品制御装置1は車両9のルームミラー4に内蔵されている。車両用電装品制御装置1は運転席に着いた運転手2の眼3の位置を車両用電装品制御装置1に内蔵したカメラで撮像して検出する。そして、車両用電装品制御装置1は、車両用電装品制御装置1と眼3との距離Lや車両用電装品制御装置1と眼3との角度Θを検出し、また、距離Lや角度Θから運転手2の座高や頭の振れ具合などの身体特性を推定する。   The vehicle electrical component control device 1 is built in the room mirror 4 of the vehicle 9. The vehicle electrical component control device 1 detects the position of the eye 3 of the driver 2 who has arrived at the driver's seat by imaging with a camera built in the vehicle electrical component control device 1. The vehicle electrical component control device 1 detects the distance L between the vehicle electrical component control device 1 and the eye 3 and the angle Θ between the vehicle electrical component control device 1 and the eye 3, and also detects the distance L and the angle. From Θ, body characteristics such as the sitting height of the driver 2 and the head swing are estimated.

車両用電装品制御装置1は、ルームミラー4やドアミラー5a、5bと眼3との位置関係を推定し、ルームミラー4やドアミラー5a、5bと眼3との位置関係や運転手2の座高や頭の振れ具合などの身体特性から、運転手2がルームミラー4やドアミラー5a、5bを見たときの視線21a、21b、21cを推定する。そして、車両用電装品制御装置1は、運転手2がルームミラー4を介して車両9の後方を見たときの視野22が適切になるようにルームミラー4の位置設定を算出する。また、車両用電装品制御装置1は、運転手2がドアミラー5a、5bを介して車両9の後方を見たときの視野23a、23bが適切になるようにドアミラー5a、5bの位置設定を算出する。   The vehicle electrical component control device 1 estimates the positional relationship between the room mirror 4 and the door mirrors 5a and 5b and the eye 3, the positional relationship between the room mirror 4 and the door mirrors 5a and 5b and the eye 3, the sitting height of the driver 2, and the like. From the body characteristics such as head shake, the line of sight 21a, 21b, and 21c when the driver 2 looks at the room mirror 4 and the door mirrors 5a and 5b are estimated. Then, the vehicle electrical component control device 1 calculates the position setting of the room mirror 4 so that the visual field 22 when the driver 2 views the rear of the vehicle 9 via the room mirror 4 is appropriate. Further, the vehicle electrical component control device 1 calculates the position setting of the door mirrors 5a and 5b so that the visual fields 23a and 23b are appropriate when the driver 2 views the rear of the vehicle 9 through the door mirrors 5a and 5b. To do.

車両用電装品制御装置1は算出したルームミラー4及びドアミラー5a、5bの位置設定と現在の位置設定とが異なる場合には運転手2にルームミラー4及びドアミラー5a、5bの位置設定の変更を通知して、ルームミラー4及びドアミラー5a、5bの位置設定を変更する。   When the calculated position setting of the room mirror 4 and the door mirrors 5a and 5b is different from the current position setting, the vehicle electrical component control device 1 changes the position setting of the room mirror 4 and the door mirrors 5a and 5b to the driver 2. The position setting of the room mirror 4 and the door mirrors 5a and 5b is changed.

このように、車両用電装品制御装置1は、運転者2の眼3の位置から推定したルームミラー4及びドアミラー5a、5bと眼3との位置関係及び運転手2の身体特性に合わせてルームミラー4及びドアミラー5a、5bの位置設定を自動的に変更することができ、運転手2がルームミラー4及びドアミラー5a、5bを介して車両9の後方を見たときの視野22、23a、23bを適切な状態に維持することができる。   As described above, the vehicle electrical component control device 1 can adjust the room according to the positional relationship between the room mirror 4 and the door mirrors 5a and 5b and the eye 3 estimated from the position of the eye 3 of the driver 2 and the physical characteristics of the driver 2. The position setting of the mirror 4 and the door mirrors 5a and 5b can be automatically changed, and the field of view 22, 23a and 23b when the driver 2 looks at the rear of the vehicle 9 through the room mirror 4 and the door mirrors 5a and 5b. Can be maintained in an appropriate state.

また、図3においては、インパネディスプレイ6、カーナビディスプレイ7、座席8に関する図示及び説明を省略したが、車両用電装品制御装置1は、インパネディスプレイ6やカーナビディスプレイ7については、推定した運転手2の視線とインパネディスプレイ6やカーナビディスプレイ7が例えば垂直になるようにインパネディスプレイ6やカーナビディスプレイ7の位置設定をすればよく、座席8については、推定した座席8と眼3との位置関係や推定した運転手2の視線から運転手2の視野が適切な状態になるように、座席8の高さや傾きなどの位置設定をすればよい。つまり、車両用電装品制御装置1はこれらの電装品についても運転者2の眼3の位置から位置設定を自動的に変更することができ、運転手2が快適に運転するために適切な状態を維持することができる。   In FIG. 3, the illustration and description of the instrument panel display 6, the car navigation display 7, and the seat 8 are omitted, but the vehicle electrical component control device 1 uses the estimated driver 2 for the instrument panel display 6 and the car navigation display 7. The position of the instrument panel display 6 and the car navigation display 7 may be set so that the instrument panel display 6 and the car navigation display 7 are vertical, for example. For the seat 8, the positional relationship between the estimated seat 8 and the eye 3 and the estimation The position of the seat 8 may be set such that the height of the seat 8 is tilted so that the visual field of the driver 2 is in an appropriate state from the driver's line of sight. In other words, the vehicle electrical component control device 1 can automatically change the position setting of these electrical components from the position of the eyes 3 of the driver 2 and is in an appropriate state for the driver 2 to drive comfortably. Can be maintained.

なお、本実施の形態の車両用電装品制御装置1は、設定変更通知部14を設けずに、設定変更通知部14の代わりにカーナビディスプレイ7やスピーカを用いて運転手2に電装品の位置設定の変更を通知すれば、車両用電装品制御装置1は小型化できる。   The vehicle electrical component control apparatus 1 according to the present embodiment does not provide the setting change notification unit 14 and uses the car navigation display 7 or the speaker instead of the setting change notification unit 14 to position the electrical component on the driver 2. If the change of setting is notified, the vehicle electrical component control apparatus 1 can be reduced in size.

また、本実施の形態の車両用電装品制御装置1は、運転手2以外の乗員の眼の位置を検出して各電装品の位置設定を変更することもできる。   Moreover, the vehicle electrical component control apparatus 1 according to the present embodiment can detect the position of the eyes of an occupant other than the driver 2 and change the position setting of each electrical component.

本発明の車両用電装品制御装置は、乗員が運転しやすいように電装品と乗員の眼との位置関係を推定し、電装品の位置設定を自動的に変更することができるので、自動車に限らず、汽車や電車など他の車両にも利用することができる。   The vehicle electrical component control device according to the present invention can estimate the positional relationship between the electrical component and the occupant's eye so that the occupant can easily drive, and can automatically change the position setting of the electrical component.
